Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Among protective jealousy is what Allah loves and hates. As for what Allah loves, it is jealousy when there is probable cause. As for what Allah hates, it is jealousy without probable cause.”

Al-Sindi said, “Protective jealousy with probable cause is suspicion of corruption, meaning, if there are signs of corruption in a situation, acting upon necessary jealousy is praiseworthy. As for when it is acted upon without any sign, acting upon it is blameworthy as it involves accusing Muslims of evil without evidence.”

عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنَ الْغَيْرَةِ مَا يُحِبُّ اللَّهُ وَمِنْهَا مَا يَكْرَهُ اللَّهُ فَأَمَّا مَا يُحِبُّ فَالْغَيْرَةُ فِي الرِّيبَةِ وَأَمَّا مَا يَكْرَهُ فَالْغَيْرَةُ فِي غَيْرِ رِيبَةٍ

قال السندي فَالْغَيْرَةُ فِي الرِّيبَةِ أَيْ فِي مَظِنَّةِ الْفَسَادِ أَيْ إِذَا ظَهَرَتْ أَمَارَاتُ الْفَسَادِ فِي مَحَلٍّ فَالْقِيَامُ بِمُقْتَضَى الْغَيْرَةِ مَحْمُودٌ وَأَمَّا إِذَا قَامَ بِدُونِ ظُهُورِ شَيْءٍ فَالْقِيَامُ بِهِ مَذْمُومٌ لِمَا فِيهِ مِنَ اتِّهَامِ الْمُسْلِمِينَ بِالسُّوءِ مِنْ غَيْرِ وَجْهٍ
